Legal claims defining the scope of protection, as filed with the USPTO.
1. An apparatus comprising: at least one processing device comprising a processor coupled to a memory; the at least one processing device being configured to: obtain a set of rebuild rate parameters for a given storage device from a storage array comprising a plurality of storage devices; and dynamically regulate a rebuild rate associated with a rebuild process for the given storage device based on the set of rebuild rate parameters obtained from the storage array for the given storage device; wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device comprises: setting a rebuild priority level for the given storage device; monitoring the rebuild process; and adjusting a number of parallel rebuild operations performed by the storage array for the given storage device in response to a change in the rebuild priority level of the given storage device; and wherein the change in the rebuild priority level is based on the obtained set of rebuild rate parameters of the given storage device and on a number of additional operations other than rebuild operations being executed by the storage array.
2. The apparatus of claim 1 , wherein obtaining the set of rebuild rate parameters for the given storage device further comprises receiving a rebuild capacity parameter and a rebuild time parameter as part of the set of rebuild rate parameters for the given storage device.
3. The apparatus of claim 2 , wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device further comprises adjusting the rebuild priority level based on a comparison of the rebuild capacity parameter and the rebuild time parameter.
4. The apparatus of claim 3 , wherein adjusting the rebuild priority level based on the comparison of the rebuild capacity parameter and the rebuild time parameter further comprises increasing the rebuild priority level when the rebuild capacity parameter is greater than the rebuild time parameter.
5. The apparatus of claim 3 , wherein adjusting the rebuild priority level based on the comparison of the rebuild capacity parameter and the rebuild time parameter further comprises decreasing the rebuild priority level when the rebuild capacity parameter is less than the rebuild time parameter.
6. The apparatus of claim 3 , wherein when the rebuild capacity parameter and the rebuild time parameter are within a predefined percentage of each other as specified by one of a system administrator and a system, the rebuild priority level is maintained.
7. The apparatus of claim 1 , wherein the plurality of storage devices are part of a RAID group.
8. The apparatus of claim 1 , further including: assigning a maximum number of parallel rebuild operations associated with the rebuild priority level for the given storage device; and based, at least in part on monitoring the rebuild process, at least one of: reducing a number of parallel rebuild operations relative to the maximum number to reduce the rebuild rate; or maintaining the maximum number of parallel rebuild operations to exceed the rebuild rate.
9. A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform steps of: obtaining a set of rebuild rate parameters for a given storage device from a storage array comprising a plurality of storage devices; and dynamically regulating a rebuild rate associated with a rebuild process for the given storage device based on the set of rebuild rate parameters obtained from the storage array for the given storage device; wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device comprises: setting a rebuild priority level for the given storage device; monitoring the rebuild process; and adjusting a number of parallel rebuild operations performed by the storage array for the given storage device in response to a change in the rebuild priority level of the given storage device; and wherein the change in the rebuild priority level is based on the set of obtained rebuild rate parameters of the given storage device and on a number of additional operations other than rebuild operations being executed by the storage array.
10. The computer program product of claim 9 , wherein obtaining the set of rebuild rate parameters for the given storage device further comprises receiving a rebuild capacity parameter and a rebuild time parameter as part of the set of rebuild rate parameters for the given storage device.
11. The computer program product of claim 10 , wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device further comprises adjusting the rebuild priority level based on a comparison of the rebuild capacity parameter and the rebuild time parameter.
12. The computer program product of claim 11 , wherein adjusting the rebuild priority level based on the comparison of the rebuild capacity parameter and the rebuild time parameter further comprises increasing the rebuild priority level when the rebuild capacity parameter is greater than the rebuild time parameter.
13. The computer program product of claim 11 , wherein adjusting the rebuild priority level based on the comparison of the rebuild capacity parameter and the rebuild time parameter further comprises decreasing the rebuild priority level when the rebuild capacity parameter is less than the rebuild time parameter.
14. The computer program product of claim 11 , wherein when the rebuild capacity parameter and the rebuild time parameter are within a predefined percentage of each other as specified by one of a system administrator and a system, the rebuild priority level is maintained.
15. The computer program product of claim 9 , wherein, wherein the plurality of storage devices are part of a RAID group.
16. A method comprising steps of: obtaining a set of rebuild rate parameters for a given storage device from a storage array comprising a plurality of storage devices; and dynamically regulating a rebuild rate associated with a rebuild process for the given storage device based on the set of rebuild rate parameters obtained from the storage array for the given storage device; wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device comprises: setting a rebuild priority level for the given storage device; monitoring the rebuild process; and adjusting a number of parallel rebuild operations performed by the storage array for the given storage device in response to a change in the rebuild priority level of the given storage device; wherein the change in the rebuild priority level is based on the obtained set of rebuild rate parameters of the given storage device and on a number of additional operations other than rebuild operations being executed by the storage array; and wherein the steps are performed via one or more processing devices.
17. The method of claim 16 , wherein obtaining the set of rebuild rate parameters for the given storage device further comprises receiving a rebuild capacity parameter and a rebuild time parameter as part of the set of rebuild rate parameters for the given storage device.
18. The method of claim 17 , wherein dynamically regulating the rebuild rate associated with the rebuild process for the given storage device further comprises adjusting the rebuild priority level based on a comparison of the rebuild capacity parameter and the rebuild time parameter.
19. The method of claim 18 , wherein adjusting the rebuild priority level based on the comparison of the rebuild capacity parameter and the rebuild time parameter further comprises: increasing the rebuild priority level when the rebuild capacity parameter is greater than the rebuild time parameter; decreasing the rebuild priority level when the rebuild capacity parameter is less than the rebuild time parameter; and maintaining the rebuild priority level when the rebuild capacity parameter and the rebuild time parameter are within a predefined percentage of each other as specified by one of a system administrator and a system.
20. The method of claim 16 , wherein the plurality of storage devices are part of a RAID group.
